Technical Field

[0001] This utility model relates to the field of ejector pin technology, specifically to an integrated turning and grinding machine for ejector pin grinding. Background Technology

[0002] An ejector pin is a tool used to fix and support a workpiece. It is usually used in conjunction with a tailstock to ensure that the workpiece remains stable during machining.

[0003] Existing ejector grinding devices require two separate steps: milling and grinding. This leads to significant time waste, increases the number of steps, and raises the workload for operators. Furthermore, these devices require manual stabilization of the ejector before the milling cutter and grinding device can be used, which is dangerous and poses certain safety hazards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an integrated turning and grinding machine for grinding ejector pins, which has the advantages of reducing operation steps and improving safety, and solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a turning and grinding integrated machine for grinding ejector pins, comprising a base, a bottom plate fixedly installed on the outer side of the base, a support plate fixedly placed on the top of the bottom plate, a slide fixedly installed on the top of the support plate, a motor I fixedly installed on the top of the slide, a lead screw I fixedly installed on the power output shaft of the motor I, a slider threadedly connected to the outer edge of the lead screw I, a support plate I and an electric gripper fixedly installed at the bottom of the slider, a support plate II fixedly installed on the outer side of the support plate I, an electric telescopic rod fixedly installed on the inner wall of the support plate II, an L-shaped bracket provided on the top of the base, a square plate fixedly installed on the outer wall of the L-shaped bracket, an electric push rod fixedly installed on the outer side of the square plate, a top block fixedly installed at the extension end of the electric push rod, an electric conveying table provided on the back of the square plate, a limit groove opened on the top of the base, a motor II fixedly placed on the inner wall of the limit groove, a lead screw II fixedly installed on the power output shaft of the motor II, and a conveying block threadedly connected to the outer edge of the lead screw II.

[0006] As a preferred technical solution of this utility model: an operating table is provided on the outer side of the base, an electro-hydraulic control lever and an electric grinding block are provided on the top of the operating table, and a pin limiting disc is provided on the outer side of the base.

[0007] As a preferred technical solution of this utility model: a controller is fixedly installed on the outside of the base, and the first motor, the electric telescopic rod, the electric push rod, the electric conveyor, the second motor, the electric gripper, the electric grinding block, and the electro-hydraulic control lever are all electrically connected to the controller.

[0008] As a preferred technical solution of this utility model: a convex plate is fixedly installed on the outer side of the square plate, a top groove is opened at the bottom of the convex plate, and a placement area is provided on the right side of the convex plate.

[0009] As a preferred technical solution of this utility model: a protrusion is fixedly installed at the extension end of the electric telescopic rod, a slot is provided in the middle of the pin limiting disc, the protrusion and the slot are on the same horizontal plane, and the clamping claw of the electric gripper is on the same horizontal plane as the slot.

[0010] As a preferred technical solution of this utility model: a clamping plate is fixedly installed on the inner wall of the base, and a milling cutter is fixedly installed on the bottom of the clamping plate.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. This integrated turning and grinding machine for ejector pin grinding utilizes the combined use of electric grippers and protrusions. A controller then operates a motor, whose power output shaft drives a sliding block. This allows the ejector pin gripped by the electric grippers to be inserted into a slot within the ejector pin retaining plate. The controller then controls an electric telescopic rod, whose extended end extends the protrusion, pushing the ejector pin into the slot. Simultaneously, the electric grinding block and milling cutter work together to perform integrated turning and grinding of the ejector pin, reducing operational steps and grinding time.

[0012] 2. This integrated turning and grinding machine for ejector pin grinding uses an electric push rod and an electric conveyor table in conjunction. The controller controls the electric push rod to work, and the extension end of the electric push rod drives the top block to extend upward, so that the top block passes through the top groove, thereby lifting the ejector pin placed in the placement area. This causes the ejector pin to pass over the top of the square plate and fall into the electric conveyor table. Through the conveyor table, it falls into the groove of the conveyor block. Then, the controller controls the second motor to work, so that the conveyor block moves closer to the electric gripper, so that the electric gripper can pick up the ejector pin in the groove of the conveyor block for subsequent ejector pin grinding.

An electric push rod 13 is fixedly installed on the outer side of the square plate 12. A top block 14 is fixedly installed on the extended end of the electric push rod 13. An electric conveyor table 18 is provided on the back of the square plate 12. A limit groove 19 is opened on the top of the base plate 2. A second motor 20 is fixedly placed on the inner wall of the limit groove 19. A second lead screw 21 is fixedly installed on the power output shaft of the second motor 20. A conveying block 22 is threadedly connected to the outer edge of the second lead screw 21.

[0017] In the above structure, the electric gripper 23 and the protrusion 29 work together, and the controller 28 controls the motor 5 to work. The power output shaft of the motor 5 drives the slider 7 to slide, so that the ejector pin held by the electric gripper 23 can be inserted into the slot in the ejector pin limiting plate 25. Then, the controller 28 controls the electric telescopic rod 10 to work. The extension end of the electric telescopic rod 10 drives the protrusion 29 to extend, so that the protrusion 29 can push the ejector pin into the slot. At this time, the electric grinding block 26 and the milling cutter 30 work together to perform a turning and grinding operation on the ejector pin, thereby reducing the operation steps and reducing the grinding time.

[0018] In a preferred embodiment: an operating table 24 is provided on the outer side of the base 1, an electro-hydraulic control lever 27 and an electric grinding block 26 are provided on the top of the operating table 24, and a pin limiting disc 25 is provided on the outer side of the base 1.

[0019] In the above structure, the electro-hydraulic control lever 27 can drive the operating table 24 to move, thereby facilitating the grinding operation of the electric grinding block 26 and the milling cutter 30 on the ejector pin.

[0020] In a preferred embodiment: a controller 28 is fixedly installed on the outside of the base 1, and the motor 5, electric telescopic rod 10, electric push rod 13, electric conveyor table 18, motor 20, electric gripper 23, electric grinding block 26, and electro-hydraulic control lever 27 are all electrically connected to the controller 28.

[0021] In the above structure, the controller 28 can control the operation of motor 5, electric telescopic rod 10, electric push rod 13, electric conveyor table 18, motor 20, electric gripper 23, electric grinding block 26, and electro-hydraulic control lever 27.

[0022] In a preferred embodiment: a protruding plate 15 is fixedly installed on the outer side of the square plate 12, a top groove 16 is provided at the bottom of the protruding plate 15, and a placement area 17 is provided on the right side of the protruding plate 15.

[0023] In the above structure, the placement area 17 allows unpolished ejector pins to be placed in the placement area 17.

[0024] In a preferred embodiment: a protrusion 29 is fixedly installed at the extension end of the electric telescopic rod 10, a slot is provided in the middle of the pin limiting disc 25, the protrusion 29 and the slot are on the same horizontal plane, and the clamping claw of the electric gripper 23 is on the same horizontal plane as the slot.

[0025] In the above structure, the claws of both the protrusion 29 and the electric gripper 23 are positioned on the same horizontal plane as the slot in the middle of the ejector pin limiting disk 25. This allows the electric gripper 23 to slide forward via the slider 7, inserting the ejector pin into the slot of the ejector pin limiting disk 25. Subsequently, the extension end of the electric telescopic rod 10 drives the protrusion 29 to extend, allowing the protrusion 29 to push the ejector pin into the slot, facilitating subsequent grinding operations.

[0026] In a preferred embodiment: a clamping plate 31 is fixedly installed on the inner wall of the base 1, and a milling cutter 30 is fixedly installed on the bottom of the clamping plate 31.

[0027] In the above structure, the milling cutter 30 facilitates the milling and grinding of the ejector pin.

[0028] Working principle: When this device is needed, the electric gripper 23 and the protrusion 29 work together, and the controller 28 controls the motor 5 to work. The power output shaft of the motor 5 drives the slider 7 to slide, so that the ejector pin held by the electric gripper 23 can be inserted into the slot in the ejector pin limiting plate 25. Then, the controller 28 controls the electric telescopic rod 10 to work. The extension end of the electric telescopic rod 10 drives the protrusion 29 to extend, so that the protrusion 29 can push the ejector pin into the slot. At this time, the electric grinding block 26 and the milling cutter 30 work to perform a one-time turning and grinding operation on the ejector pin, thereby reducing the operation steps and grinding time. The electric push rod 13 and the electric conveyor table 18 are used in conjunction, and the electric push rod 13 is controlled by the controller 28 to work. The extension end of the electric push rod 13 drives the top block 14 to extend upward, so that the top block 14 passes through the top groove 16, thereby lifting the ejector pin placed in the placement area 17. This causes the ejector pin to pass over the top of the square plate 12 and fall into the electric conveyor table 18. Through the conveying of the electric conveyor table 18, it falls into the groove of the conveyor block 22. Then, the controller 28 controls the motor 20 to work, so that the conveyor block 22 moves closer to the electric gripper 23, so that the electric gripper 23 can pick up the ejector pin in the groove of the conveyor block 22 for subsequent ejector pin grinding work.
